Far-field eddy current scanning probe device for air cooler with finned tube

The utility model relates to the technical field of eddy current scanning, in particular to a far-field eddy current scanning probe device for an air cooler with a finned tube, which comprises a mounting column, a lead screw is rotatably connected in the mounting column, one side of the outer surface of the lead screw is in threaded connection with a moving block, and the moving block is in threaded connection with the mounting column. A plurality of first limiting pieces are fixedly connected to one side of the outer surface of each movable block, every two first limiting pieces form a group, a first through hole is formed in one side of each first limiting piece, a rotating shaft is fixedly connected to the bottom of the lead screw, and a handle is fixedly connected to one side of the rotating shaft. Compared with the prior art, the probe device has the advantages that the thickness of the probe device is changed by the supporting assembly through a series of matching, the distance can be adjusted according
